European frog-bit (Hydrocharis morsus-ranae) is a free-floating aquatic plant with multiple miniature lily pad shaped leaves. This prolific invasive species is spreading along the shorelines and wetlands of Lakes Erie, Huron and Ontario. European frog-bit was brought from Europe to the Central Experimental Farm in Ottawa in 1932 as an ornamental plant. By 1939, it had escaped and spread to the Rideau Canal in Ottawa, Canada (Catling and Dore, 1982). Since then it has continued to spread into several rivers, Lake Ontario, Lake Erie, Lake Huron and other inland waters. Click on the two links below to access the full story.
